There is a camera E-Buckmail, I have 2 of them, my land is 50 miles from my home and I can check my picytures anywhere there is a computer or with a Blackberry phone.They are IR at night [no flash], I have mine hooked to a deep cycle batteries and have put a couple of solar panels with it to keep the batteries charged. They cost about $600 and you need to add thge cell service, but you don't have to pay gas to get pictures. I have even checked mine while in Canada fishing.
I have been using them for over 1 year, you can check on their website, e-BuckMail.com Home Page
. They take a lot of pictures but I just delete them.
